IEEE 802.11 MAC, called the Distributed Coordination Function (DCF), employs carrier sensing to effectively avoid collisions, but this makes it difficult to maximally reuse the sp...
We consider a wireless ad-hoc network with random ALOHA transmissions between nodes. However nodes can decide to use the Request-to-Send (RTS) / Clear-to-Send (CTS) protocol for oc...
—We consider a point-to-multipoint cognitive radio network that shares a set of channels with a primary network. Within the cognitive radio network, a base station controls and s...
